Instructions on how to use these Charts: Determine Mean Roof Height,h,which is top of roof for flat roofs or the mean roof height for pitched roofs. Find your least
horizontal dimension for your building,not including a overhang if it occurs. Calculate the value of,a,=10%of least horizontal dimension or 0.4*h,whichever is
smaller,but not less than either 4%of least horizontal dimension or 3 feet.If your roof height is less than 30 feet, but not exactly 15,20,or 25 feet,you will need to go
to the next higher roof height.If your Mean Foof Height is higher than 30 feet,these charts do not apply. Review the diagram which illustrate the wall and roof zones
and determine the wind zone in which the component is located. Determine the tributary area of the component.If the tributary area falls in between values,use the
value of the smaller tributary area. Select the positive and negative wind pressures corresponding to the wall or roof zone where your component is located. Door
pressures shown are for the most common door sizes and are worst case for heights<=30 Feet.
